Many companies that made the software we used to grow and love lost their touch a long time ago and the only company that seems to have things together is what the professional companies are currently using and obviously thats not IPB nor will it ever be with the disaster that is IPB 4.0. For reasons many are aware, I'm not naming who the competition is and I'm not stating why IPS got worse over the years because this has been brought up enough times and I've given up on IPS.

There are so many important issues IPS hasn't fixed for many years that bringing up something like this... especially with the mess that is 4.0 is pointless. You are using a super high resolution display that the average person still does not use. Factor in Mobile Devices and there really is nothing you can do. All Browsers display these images this way because of the CSS Styling... which you are always welcome to change.

​Looks like you'll be forced to deal with Mobile since they developed the 4.0 skin this way. Your only other option is submit a bug report and have them fix this because that resolution while being low shouldn't be Mobile, even if there are Mobile Devices that have that resolution or higher!

At the very bottom there is an UP Arrow to scroll up the page. With some modification, you can have this button/link float at the bottom of the page.
As far as the search functionality, It's been a mess for years. Until they completely revise how it works, It's going to continue to be useless.
